It is not the holy grail of replacements so it will work for some people but not all. "Ride Command" works on their system but have not heard if BRP Go will work.
I'm going with the Trail Tech Voyager Pro gauge on my Gen5. All the GPS you'd expect, but also Polaris compatible buddy tracking as well as additional sensors (RPM, engine temp, air temp, etc. It mounts on a RAM mount or on the glovebox extension just like a Garmin.
Shop Voyager Pro GPS for your motorcycle, ATV, UTV, SxS, and snowmobiles at Trail Tech. Voyager Pro has a touchscreen, topo maps, integrated gauges, and is compatible with Polaris RideCommand group ride.
